So I picked up a yamaha g9 but the engine is shot, so I'm looking to replace it with another engine. I read the stock engine is a 285cc 8.5hp engine, so will any 285cc 8.5 hp or greater engine make it run like stock/slightly better?

I thought the 285 was 9.4hp, but yeah something like that. The clone is a great deal at about $300 for a brand new 420cc engine. If you get the $50 adapter to put the clutch on and some odds and ends to make a mount and plumb the airbox and exhaust you are set. Even the 390cc clone should have more power at 13hp, but often not that much cheaper than the 420 which has more torque. They are a lot more fun, but it is a project to get everything hooked up. There are various threads here for doing a G9 clone.

Odds are you might pay more than 300 for a stock good running engine that is not burning oil.

I was going off the specs in the manual for the 285/8.5 information. I'm looking at the clones now, but I wasn't expecting to get an actual yamaha g9 stock engine, I was thinking 10 hp snowblower or something, but that might be more of a project.

That would be a lot of power, check out the section on sled engine swaps. Problem with sled engines is you need the pipe (exhaust) to make the power they have, and if you mod the pipe you have to keep the same length and shape but you can rotate it and weld it back up.
